Key areas of work visas

Essential classifications, statutory standards, and relief avenues covered in this guide.

Common Nonimmigrant Work Visa Classifications

H-1B, L-1, O-1, TN, and E-3 categories

H-1B specialty occupation visas require at least a bachelor’s degree in a specific field and are subject to an annual congressional cap and electronic lottery, unless the employer is cap-exempt (such as universities and nonprofit research institutions).

L-1 intracompany transfers allow multinational corporations to transfer managers and executives (L-1A) or specialized knowledge staff (L-1B) from foreign offices. O-1 visas reward individuals with extraordinary ability in science, arts, education, business, or athletics. Canadian and Mexican professionals may qualify for streamlined TN status under USMCA.

Labor Condition Applications (LCA) and Wage Requirements

Prevailing wage levels, public inspection files, and employer compliance

Before filing an H-1B, H-1B1, or E-3 petition, the employer must submit a Labor Condition Application (LCA) to the U.S. Department of Labor certifying that they will pay the required prevailing wage and that hiring the foreign worker will not adversely affect domestic workers.

This page explains how the work visa process generally works. It is general information, not legal advice, and it does not create an attorney-client relationship. Work visa outcomes depend heavily on individual facts and on current policy, both of which change. Speak to a licensed immigration attorney about your own situation.
